Synthesis and Performance Study of Tris(β-Methylglycidyl) Isocyanurate

以氰脲酸、β-甲基环氧氯丙烷为原料,在相转移剂的催化作用下合成了三(β-甲基环氧丙基)异氰脲酸酯(TMGIC)。并探讨了催化剂的种类、用量、反应温度、反应时间和环化温度对产品收率的影响。结果表明,采用四甲基溴化铵作为相转移催化剂,用量为原料氰脲酸的4%,合成反应温度为120℃,反应时间为3 h,环化反应温度为50℃条件下,TMGIC产品的收率达到78.9%,产品各项性能均达到市售TGIC产品的要求,可以替代TGIC产品来使用。

The tris（β-methylglycidyl） isocyanurate（TMGIC） was synthesized with cyanuric acid and beta-methyl epichlorohydrin under catalytic action of phase transfer agent. The effects of catalyst types, dosage, reaction temperature, reaction time and cyclization temperature on the yield rate were investigated. The results showed that the yield rate of TMGIC was up to 78.9%. All properties could meet the requirements for commercial products and TMGIC could be used to substitute TGIC products in case that tetramethylammonium bromide was used as the phase transfer agent with the dosage equal to 4% of cyanuric acid, the synthesis reaction temperature was 120 ℃, the synthesis reaction time was 3 h and the cyclization reaction temperature was 50 ℃.
